WINDow-SASH BOWER.

Application led May 16, 191'6. Serial No. 97,879.

4iication.

This invention relates to builders hardware, and more especially to bowers for sashes or similar swinging members hinged within other members; and the object of the same is to produce a device of this character having means for positively locking the swinging member in various positions excepting that it will not lock the same when closed. For this latter purpose a separate latch or lock is desirable, and obviously this may not work when the swinging member `is in any other position than closed. For details, reference is made to the following specification.

1n the accompanying drawings:

Figure 1 is a vertical section through a window and an edge elevation of one swinging sash bowed outward by means of my invention, Figs. 2 and 3 are enlarged horizontal and vertical sections through the side rail of the swinging sash and the spring bolt for locking the bower thereto, and Fig. 4 is a perspective detail of one of the pivot plates showing the bower across it in dotted lines.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawings in detail, A designates generally a window frame which is of the ordinary well known construction having the intermediate or parting strip 10 and guide strips 11, respectively, at each side thereof, as usual, for the slidable reception of the upper and lower main sashes 12 and 13 respectively, which can be raised and lowered in the ordinary well known manner.

1n each frame of the upper and lower sashes is mounted an auxiliary or supplemental swinging sash 14 which, together with the main or sliding sash frame, is rabbeted, as at 15, for the tight fitting of the swinging sash 14 within the main or sliding sash to render the same weathertight when the swinging sash is closed.

Speciicaton of ietters Patent.

Patented Jan. S, 1918.

Each swinging sash 14 has mounted there- `in a sash pane or glass 16as usual, and

countersunk within opposite outer side edges oi the swinging sash 14 to lie flush with the ,said edges are pivot; plates 17 which are located `substantiallyi centrally of the said Vswinging sash and are formed with headed pivots 18 which engage and work within slots 19 formed longitudinally in hanger arms 2O whose upper` ends are mounted'on pivots 21 in the oppositesides of each main or sliding sash Vat the inner edges thereof, the said inner edges of the sides of the main ior sliding sash being cut away` in correspondence with the length of the arms 20 to accommodate the same when the swinging sash 14 is closed so that the said arms 20 will lie flush with the inner edges of the main or sliding sash. Each main or sliding sash has fitted in the side or vertical rails thereof suitable hand-released latch devices 22 which serve to lock the swinging sash 14 closed to prevent the opening thereof from the outside of the window for intrusion.

Mounted in the side or vertical rails of each swinging sash 14 are locking bolts 23 which Work through apertures 17 in the pivot plates 17 for positive engagement with any one of a series of apertures or holes 24 formed in each hanger arm 20 alongside its slot 19 so as to lock the swinging sash 14 in angular adjusted position and at any desired inclination relative to the main or sliding sash. By preference the bolt is normally projected through the medium of a coiled expansion spring 24 operating upon a shoulder 25 on said bolt and confined within a recess 26 formed in the vertical or side rail of the sash 14 so that in this manner the bolt will be positively moved to locking position for the fastening of the movable sash in adjusted position. The bolt 23, at its inner end, is formed with a knurled head 27 which permits the convenient manipulation thereof for the retracting of the same against the resistance of the spring 24 to release the bolt to permit the movement of the swinging sash.

An important feature of the present invention is the fact that one latch can not be operated except when the other is idle. The bolt 23 holds the sash open, and at this time the latch 22 obviously can not work.

Gopies of this patent may be obtained vfor Varm 20 now hangs across the plate 17 as seen in dotted lines in Fig. 4, and the bolt 23 is directly above the pivot `18. V'Hence it is impossible for the action of one latch to prevent the action of the other, and tis never necessar)v to actuate more than one pair of latches before moving the sash.

It will be noted that when the sash 14 is swung to open position the lower edgethereof rests upon the main or sliding sash and is hingedly supported but withoutthe necessity for hinges, and init/his manner thel said swinging sash is removably mounted therein; When the swinging sash is open it en ables the easy cleaning ofthe pane of Vglass 1G therein without necessitatingthe cleaner assuming hazardous positions at the outside ofthe windowl as is usual.

From the foregoing description, taken in connection with the accompanying drawings, the construction andoperation ,of my window sash construction` will Vbe readily Vapparent and, therefore, a more extended explanationhas been omitted.

Having thus "describedfi'ny invention, I claim: The combination with a frame member, and a` swinging member hingedly mounted at its lower end therein; an armstanding between the side bars of the memberswhen closed and having a longitudinal slotand a. series oi holes alongside the same, means for pivoting one"V end of the arm 'to' one ineinber, a plate on the othe'rmember having a pin sliding in said slot and an aperture adapted to registerv successively with said holes as' this member-is moved and to pass over the end ot' `the slot 'as it 'is`c`losed, land ture, for the purpose set forth.V

In'testimony whereof I my signature.`
